CLOSURE DEvIon FOR coiv'rAinnns FOR LIQUIDS,

Specification of Letters Patent. Patented 19 192() Application filed January 2,1920. Serial No. 349,121

l '0 aZZ whom it may concern:

Be it known that I, JOHN BLIss,a subject. of the King of England, residing in London, England, have invented certain new and useful Improvements in Closure Devices for Containers for Liquids, of which the following is a specification.

This invention is for improvements in or relating to a closure-device for containers poured from or into the container. The invention is particularly applicable to oilor petrol-containers which are provided with a pouring spout extending from the mouth wherein the screw-stopper fits. When these containers are carried on a motor-car or are left standing, dust accumulates in the spout (or other cupped-portion) adjoining the mouth, and consequently this is liable to get int-othe lubricant or other contents when the container is next used.

According to this invention, a closuredevice of the type described for containers comprises a screw-stopper and a plate carried thereby which is so placed and dimensioned that when the stopper is screwed home it lies over the cupped portion adjoining the mouth of the container with which the liquid comes in contact when pouring from or filling the container.

Preferably the plate is so mounted on the stopper that it can swivel on the same.

The term cupped-portion wherever it occurs herein is used to denote any trough or well-like portion, with or without a spout or lip, which is adjacent to the mouth of the container and either stands above or is recessed to a lower level than that of the mouth and with which the liquid is likely to come into contact either when pouring from or filling the container. 7 In the accompanying drawings which illustrate one method of carrying out this invention I Figure 1 is a perspective view of the stopper'with the plate attached, viewed from the top, and l Fig. 2 is a perspective-view of the same parts viewed from the under-side.

Thestopper A may be of the usual form which is hollow and made from thinsheet metal. Surrounding the stopper is a plate 'B-which is shaped to cover the usualspout and that cupped portion adjacent to or surrounding the mouth ofthe container, which mouth 'is screw-threaded to receive the" stopper. -The plate B is free to swivel on the stopper but is prevented from being withdrawn from the outer end of the stopper by the usual milled bead A whereby the stopper is gripped for turning it, and is prevented from displacement from the inner end of the stopper by a rib A These stoppers are usually made up in two parts, the main body being formed as a cup, the open end of which constitutes the Outer end of the stopper, and then the mouth of the cup is covered in by a disk which is spun or clamped over the said outer end. The plate B can thus be introduced into position before the closing-plate is fixed on the outer end, and then the said closing-plate which provides the milled bead, willprevent its withdrawal.

The plate B has a flange B at the edge always retained on the stopper, and when screwing the stopper home all that the operator has to do is to bring the plate into register with the mouth and its spout to insure that the same. shall be covered. The flange B is sufiiciently deep so that when the stopper is secured home the plate B cannot be lifted from the spout and moved angularly in relation thereto as the milled bead A then keeps the plate down.

It will be appreciated that the plate may be of various shapes according to the kind of mouth the container is provided with and various means may be used to keep it on the stopper provided such means permit'it to swivel unless themouth ofthe container is such that it can be covered byla circular plate, in which case the plate need not swivel but can be a fixture on the stopper. To use a circular plate for a mouth having a spout would necessitate the employment of a large plate relatively to the size of the stopper, which would be liable to become damaged and prevent the stopper from being properly screwed home.

The flange on the plate in addition to effecting registration with the spout, also serves to prevent the entrance of dust underneath the plate, but the fiange could obviously be interrupted if desired, and might in some cases merely take the form of two projections arranged to register with opposite sides of the spout.

hat I claim as my invention and desire to secure by Letters Patent is l. A closure device for liquid containers having a spout extending laterally from the month, which closure device comprises a screw stopper carrying a plate that is situated at right angles to the longitudinal axis of the stopper, is secured against axial movement relatively to the stopper but is rotatable thereon, is shaped to cover the said spout, and is so positioned on the stopper that when the latter is screwed home and the plateis'brought over the spout, it is held in place bythe stopper, substantially as described.

2. A closure device for liquid containers having a spout extending laterally from the month, which closure device comprises a screw stopper carrying a plate that is situated at right angles to the longitudinal axis of the stopper, is secured against axial movement relatively to the stopper but is rotatable thereon has a lateral projecting lip shaped to. register with the said spout, and-has a dependent flange to inclose the sides ofthe mouth of the container and the spout, substantially as described.

In testimony whereofl aflix my signature. 1
